Access Heights

A Building Maintenance Unit (BMU) is a form of suspended access equipment intended to be permanently installed and dedicated to a specific building or structure.

The cradle of the roof-powered BMU is lifted and lowered with 2 or 4 suspension ropes. These wire ropes are wound in a single or multi-layer drum type hoist located in the roof car machine housing. The wire ropes used for the roof-powered gondolas are classified as double-active rope suspension systems and a rope safety factor greater than 12 ensures that we comply with the EN 1808 norms.

In case of emergency, the drum hoist unit in the roof car could be manually released and the cradle safely lowered to the landing ground below.

Our roof-powered Chameleon cradle is a revolutionary product, since we are the first company in Asia to incorporate the drum type hoist in the cradle. The capacity of the hoist unit is 500 kg with a lifting height up to 160 m.

Compared to other self-powered cradles using traction hoist(s) on the market, MHE-Demag drum hoist cradles offer higher safety and reliability, are quiet to operate, as well as eliminating wear and tear to the ropes and hoist parts.

One end of the wire ropes is wound to the hoist drum located in the cradle and the other end is attached to the suspension rig above. The suspension rig is generally a trolley unit, a monorail with a traversing trolley or another rigging system, e.g. davits, fixed to the building, from which a cradle may be suspended.

In case of power failure, the drum type hoist unit in the cradle could be manually released, allowing the cradle to descend safely to the landing ground below.

Working at heights is inherently dangerous. Our fall arrest safety line systems provide continuous protection throughout the period when the user is exposed to a risk of falling. The fall arrest system stops free fall and limits the arresting force to the user.

Stabiliser assisted work platforms employ outrigger legs to provide stability during operation. Typically these machines are built to work at great height, with some machines capable of working to a maximum height of 52 metres.

The outrigger legs deploy during operation and it raises up the entire AWP while the machine is in operation. With this, the machine can be built more compact and lightweight for both travelling and stowing, compared with self-balanced type work platforms.

Another advantage of stabilisers is also that the outrigger can be deployed on terrains of a different ground height enabling the AWP to operate and work on uneven ground.

We offer a wide range of Stabiliser Assisted Access Work Platforms ranging from a 10 metre up to a 52 metre working height, with a horizontal outreach of up to 20 metres. It can be powered by direct AC supply, battery driven, diesel driven or a combination of both battery and diesel.

When works are to be carried out safely at a height where high mobility is needed, a self-balanced AWP is recommended.

The self-balanced AWP is built heavier and with a wider body structure to counterbalance the stability of the machine while in operation. It would allow the operator to drive the machine when the platform or boom is in its up/raised position.

We offer a wide range of self-balanced access work platforms ranging from a 10 metre up to a 21 metre working height and with a horizontal outreach of up to 13 metres.

Self-balanced AWPs can be battery driven, diesel or petrol driven or can be a combination of both battery and diesel, or battery and petrol.

In general, our self-balanced, self-propelled boom lifts can be categorised as below:

We have a complete range of work platforms suitable for indoor work access, such as ceiling work, window cleaning, light changing, decoration and banner hanging, as well as many forms of other work requiring safe access in high, inaccessible places.

Our aerial platforms can be used in all types of commercial buildings such as high rise offices, shopping centres, airports, hotels, stadiums, museums, recreation parks and others.
